Inquires into assessment items classified as "extended pieces of work" in applicable mathematics in Western Australia. Identifies opportunities for graphics calculator use in extended pieces implemented in schools. Concludes that availability of the technology has widened the scope of approaches used in extended pieces of work in…

In this article, the authors describe how to use a TI-73/83/84 graphing calculator and Vernier's LabPro/CBL2 probe system to take pH readings. This is not an endorsement of these products, but simply the authors' attempt to give readers an idea of what is involved in using this technology in the classroom. This activity can be accomplished using a…

Graphing calculators and data collection technology was integrated in an undergraduate science methods classes for preservice elementary school teachers. The study investigated whether preservice teachers' knowledge and comfort with the use of graphing calculator technology and their perspectives in the use of graphing calculator technology were…

This essay describes the role of graphing calculators in mathematics reform. Among the topics discussed are the history of graphing calculators in mathematics education, recent technological innovations, and professional development opportunities. The case is made for a balanced approach between calculator use and paper-and-pencil techniques.…

Materials are included for three workshops and 26 lessons. Lessons are organized by common mathematical topics making it…

This document presents keystrokes for the Texas Instrument (TI-83) graphing calculator. After presenting some basic TI-83 keystrokes, activities for student practice are listed. This is followed by keystrokes for TI-83 advanced functions such as evaluating function values, finding the zero of a function, finding the intersection of two graphs,…

In this age of digital technology, calculators, computers, and educational software, calculator-based laboratories have become important elements in the learning and teaching of mathematics. This digest provides an annotated listing of World Wide Web resources and contact information for organizations pertaining to technology use in mathematics…

Considers the impact of the introduction of graphic calculators into assessment within the International Baccalaureate Diploma. Discusses difficulties that arise in the development of practice questions, how these difficulties were resolved in the questions that appeared on the examinations, and problems of different calculator syntax. (Author/KHR)

Uses a Calculator-Based Ranger and a graphing calculator in problem-solving mode to introduce an exploration of graphing-related concepts including intercepts, slopes, and rate of change. (YDS)

Describes the use of calculator based laboratory (CBL) technology in monitoring the process of chemical reactions. Explains the estimation of infinity readings and criteria to choose t values. (YDS)

Many students have difficulties in interpreting position versus time graphs. Presents an activity involving calculator-based motion labs that allows students to bring these graphs to life by turning their own motion into a graph that can be analyzed, investigated, and interpreted in terms of how they actually moved. (ASK)

Investigates secondary mathematics teachers' use of the graphing calculator in their classrooms. Examines whether algebra teachers are currently using this technology in their classrooms, their perceptions toward the technology, and any changes in the curriculum or instructional practices. Indicates that the use of the graphing calculator is still…

Stresses the value of graphing and computer algebra systems calculators when teaching about waves. Discusses how to input data into these calculators. Highlights the Texas Instruments' (TI) Web site at http://www.ti.com. (YDS)

Presents six examples illustrating both the way in which the level of mathematical demand has been raised, and ways in which the response has sometimes been inadequate with the use of graphing calculator technology. (ASK)

Describes how the meaning of a tool was constructed by students and their teacher, and how students used the tool to construct mathematical meaning out of particular tasks through a qualitative classroom-based study. Suggests that the nature of the mathematical tasks and the role, knowledge, and beliefs of the teacher influenced the emergence of…
